BACKGROUND ART

Conventionally, as a prefabricated house, ones using a prefabrication construction method configured so as to perform only an assembling work by manufacturing and processing members at a factory in advance without performing processing at a construction actual place are well known.

Examples of such a prefabricated house will be shown below.

1) Japanese Utility Model Laid-Open No. S60-137001 (see PTL 1) shows an assembling shed configured so as to provide notches at side portions of panels and perform assembling using connecting fittings having notches coincident with the notches at the side portions.

2) Japanese Patent Application Laid-Open No. S60-141937 (see PTL 2) shows a prefabricated house provided with

(a) a roof portion constructed by assembling a required number of wooden roof panels formed so as to have standardized shapes and sizes; and

(b) a wall portion constructed by assembling a required number of wooden wall panels formed to have standardized shapes and sizes without using pillars, characterized in that

(c) mounting portions are provided on inner faces of the roof panels at portions contacting with upper end portions of the wall panels, the roof portion is placed on the wall portion, and the mounting portions and the wall panels are fixed to each other.

3) Japanese Patent Application Laid-Open No. S48-100919 (see PTL 3) shows a prefabricated building characterized in a rigid-frame structure obtained by arranging one kind or a plurality of kinds of block members formed in an L shape, a T shape, z shape, across shape or the like by integrating a pillar and a bearing wall at corner portions or important positions of the building and connecting the block members using beams or wall panels.

Further, a prefabrication construction method including manufacturing panels for respective members, assembling them in a final structure at a factory in advance, transporting the final structure by a transport vehicle as it is, and performing only a work for installation at an actual place is also used.

However, when a building having a certain degree of large size such as a container house is assembled to a final structure in advance and the building is transported by a transport vehicle as it is, such a problem often tend to occur that a large-sized vehicle carrying the building thereon cannot pass through an ordinary road due to road circumstances in Japan, so that population of such a prefabrication construction method is blocked due to domestic circumstances.

In view of these circumstances, it is necessary to adopt a prefabricated house using a prefabrication construction method including manufacturing and processing members at a factory in advance, such as described above, and performing only a work for assembling the members at a construction actual place without performing a processing thereat, but problems described below are recognized in the prefabricated house using the conventional prefabrication construction methods.

a. When a plurality of prefabricated houses are constructed so as to be arranged in parallel, the respective prefabricated houses arranged with doors, windows, and the like uniformly are stood in parallel, because there is no degree of freedom in layout for an opening portion such as a door or a window, which results in much large bad reputation from residents thereof.

b. When a plurality of prefabricated houses are built in parallel, the prefabricated houses having a uniform room layout are stood in parallel, because there is no degree of freedom in layout for a floor, which results in much large bad reputation from residents thereof.

c. It is possible to change an arrangement of wall members to perform layout to some extent, but since arrangement of an opening portion such as a door or a window is not changed, a uniformity problem such as described above is not solved.

In view of these circumstances, in Japanese Patent Application No. 2012-91265 (see Japanese Patent Application Laid-Open No. 2013-221242), the present inventor provided a prefabricated house where since, regarding not only a floor layout but also a layout of an opening portion such as a door or a window, their arrangements can be changed, or an outer face and an inner face or an upper side and a lower side can be reversed, variations regarding not only the layout of a floor but also the layout of opening portion such as a door or a window can be increased rapidly, and even when a plurality of prefabricated houses are constructed in parallel, the prefabricated houses having an uniform room layout are prevented from being arranged in parallel, which provides a feeling of large satisfaction to residents thereof.

DESCRIPTION OF EMBODIMENTS

An embodiment of a prefabricated house according to the present invention will be explained in detail below with reference to the drawings.

FIG. 1 to FIG. 5 show a first embodiment of a foundation structure of the preassembled house according to the present invention.

A steel-frame foundation 101 shown in FIG. 1 is provided with a structure where vertical frames 103 and a horizontal frame 104 composed of H-shaped steels are arranged inside an outer frame 102 obtained by connecting H-shaped steels in a rectangular contour and attaching inclined frames for reinforcement 105 to four corners of the rectangular contour.

Then, between the respective outer frames 102, the vertical frame 103 and the horizontal frame 104, a coupling piece 106 extending from an H-shaped steel is caused to abut on another H-shape steel to be connected thereto by bolts and nuts 107, as shown in FIG. 2.

Incidentally, FIG. 2 shows that a supporting frame 108 is installed on a foundation, and a proper portion of the steel-frame foundation 101 is mounted on the supporting frame 108 via a seismic isolation rubber 109, so that earthquake-resistance support is achieved. Therefore, the prefabricated house can be constructed rapidly while sufficient earthquake resistance is brought to the prefabricated house. FIG. 3 shows positions of the supporting frames 108 to which the steel-frame foundation 101 is mounted. As the respective supporting frames 108, steel-frame made members are used at least at four corners and at positions on which a load acts, and wooden members can be used as the other supporting frames.

FIG. 4 shows a state where outer wall members 12, outer walls, and climbing beams for a roof 110 have been mounted on the floor member 11, where a fixing groove 111 is formed on an upper portion of the climbing beam 110 so as to extend a longitudinal direction of the climbing beam 110, and firm mounting of a roof member 15 shown in FIG. 5A can be performed using a ridge (not shown) formed on the roof member 15. FIG. 5B shows a ridgepole 112, where the roof member 15 can be mounted along an inclination face of the mountain-shaped ridgepole 112.

Thus, since the outer wall members and the inner wall members have been erected from the four peripheries of the floor member 11, and the mountain-shaped roof member 15 has been mounted on the outer wall members via the climbing poles 110, more rapid completion can be achieved as the prefabricated house.

Further, upper portions of the outer wall members and the inner wall members except for a bath room constitute an open ceiling, so that ventilation performance as the prefabricated house is much excellent.

A layout of the prefabricated house of the present invention shown in FIG. 6 to FIG. 13 is provided with the floor member 11 approximately rectangular as a whole, outer wall members 12, 13 erected from four peripheries of the floor member 11, respectively, as a pair of long outer wall members and a pair of short wall members, inner wall members 14 partitioning the floor member 11, a mountain-shaped roof member 15 mounted on the outer wall members 12 and 13.

A panel P constituting the respective members is one configured by attaching composite panels C to both sides of core members S arranged at predetermined intervals and filling heat insulating materials H in hollow spaces between the composite panels C, and attaching a desired surface material (not shown) to an outdoor face or an indoor face, respectively.

As the heat insulating material, an inorganic-base heat insulating material such as glass wool or rock wool, or an organic-base heat insulating material composed of foamed material such as closed-cell urethane foam, or phenol foam, frame-retardant polystyrene foam can be used. By the way, when the closed-cell urethane foam is filled in the floor member 11, the outer wall members 12 and 13, the inner wall member 14, and the roof member 15 to be used, buoyancy is provided thereto, so that when the prefabricated house has been swallowed up by Tsunami in the vicinity of the seashore or a muddy stream at a river, even if the house is flown, it does not sink under a water surface, which is considerably significant regarding lifesaving, or the other disaster countermeasures.

As shown in FIG. 6 to FIG. 9, in the outer wall members 12 and 13 erected from the four peripheries of the floor member 14, the long outer wall members 12 is each configured by connecting a plurality of outer wall member panels 12-1, 12-2, and 12-3 divided into at least three portions and the short outer wall members 13 are each configured by connecting a plurality of outer wall member panels 13-1 and 13-2 divided into at least two portions.
